Abstract

A power tool having multiple wireless communication states, the power tool comprising a motor, a battery pack interface that selectively receives a battery pack, a backup power source, a wireless communication controller coupled to the backup power source and the battery pack interface, a switching network coupled between the motor and the battery pack interface, an actuator and a controller coupled to the actuator and the switching network. The wireless communication controller includes a wireless transceiver and a processor. The wireless communication controller is configured to operate in an advertisement state when the wireless communication controller is coupled to and powered by the backup power source. In the advertisement state, the wireless communication controller is configured to transmit an advertisement message including a unique tool identifier. The controller is unpowered when the wireless communication controller is in the advertisement state. The controller is configured to control the switching network to apply power from the battery pack to drive the motor based on actuator activation.
